Description

An electric fitness bicycle with automatic speed adjustment

technical field

The invention belongs to the technical field of electric bicycles, in particular to an electric bicycle with the function of fitness exercise.

Background technique

With the improvement of people's material and cultural living standards, people pay more attention to physical and mental health and environmental protection. It is the general trend to choose to burn fat instead of burning gasoline. The use of bicycle fitness is more and more accepted by the public, but the current fitness There are following deficiencies in the method:

First of all, ordinary exercise bikes are mostly placed indoors or in fixed places, occupying a large area, and cannot be moved at will. Therefore, indoor fitness can only be carried out at a specific time and place, not only cannot be fully in contact with nature, but also makes the exercise process obtain good air quality , and it is not conducive to the promotion and popularization of the sport;

Secondly, ordinary outdoor cycling has its merits, but because of its limited cruising speed, some occasions cannot adapt to the increasingly accelerated pace of life and work like faster conventional electric vehicles. In order to improve efficiency and save time, people have virtually ignored the opportunity of cycling.

And current electric bicycle is regarded as good means of transportation by people because of its simple driving, convenient and fast, green environmental protection, but on the other hand we find that electric bicycle hardly has the effect of exercise and fitness. Therefore it is very valuable to develop a kind of automatic speed-regulating electric exercise bicycle that can not only reach the body-building exercise effect, but also adapt to the increasingly fast pace of life and work so as to save time.

Contents of the invention

In order to solve the technical problems in the known technology, the present invention provides an automatic speed-adjustable electric exercise bicycle, which can be used not only as fitness equipment at ordinary times, but also as an efficient walking tool.

The technical scheme that the present invention takes for solving the technical problem existing in known technology is:

An electric exercise bicycle with automatic speed adjustment, comprising an exercise system installed on a vehicle body and wheels, a motor system for driving the wheels, an exercise speed measuring sensor, automatic and manual speed regulators, a controller system and a power supply system.

First, the rider's cycling pedals drive the fitness system to rotate, and the speed of rotation formed by the pedals is collected synchronously through the fitness speed sensor, and the digital signal of the rotation speed is increased and amplified by a certain number of times through the automatic speed regulator. Then the multiplied and amplified digital signal is sent to the controller system, and the controller system accurately controls the starting, acceleration, deceleration and braking of the motor. The motor converts electrical energy into mechanical kinetic energy to drive the electric vehicle.

The signals of the entire control circuit, including acquisition, conversion multiplication, transmission, and feedback, are all synchronized in real time. The rider drives the exercise wheel like riding on a traditional bicycle, and the controller starts the battery to "discharge". The faster the rider's pedaling frequency, the faster the electric bicycle travels, and vice versa, so that Give the rider a personal sports experience that the car moves with the feet.

The present invention has the following outstanding advantages:

1. Compared with the conventional exercise bicycles, the electric exercise bicycle of the present invention is not limited by the time and venue for riding, which is conducive to the popularization of outdoor sports;

2. The electric fitness bicycle of the present invention can realize stepless continuous linear amplification output between the actual driving speed and the fitness exercise speed;

3. Compared with ordinary pedal bicycles, the electric fitness bicycle of the present invention is driven by a motor, which can improve the efficiency of life and work while exercising, saving precious time, and is an excellent means of transportation;

4. The kinetic energy generated during the fitness process can also charge the battery, which is environmentally friendly and energy-saving.

Detailed ways

In order to further understand the content, characteristics and functions of the present invention, the following examples are given, but these examples do not limit the protection scope of the present invention.

Please refer to Figure 1, an electric exercise bicycle with automatic speed adjustment, including an exercise system and wheels installed on the car body, a motor system that drives the wheels, an exercise speed sensor, automatic and manual speed regulators, and a controller system and power supply system.

The pedaling movement of the rider is transmitted to the fitness system to generate a rotational speed, which is collected by the fitness speed sensor and converted into a digital signal, which is transmitted to the automatic speed controller to achieve a certain multiple of increase and amplification, and then the multiplied and amplified digital signal is sent to the control system. In the inverter system, the duty cycle of the output square wave is changed accordingly to change the average current power on the load from 0 to 100%, and the output voltage can be continuously adjusted steplessly to realize the speed regulation of the drive motor.

According to relevant laws and regulations, the maximum driving speed range of different electric bicycles is 20-60km/h on a flat road without wind. Assuming that the highest rated driving speed generated by the mechanical kinetic energy provided by the driving motor is V _max , the corresponding output voltage is U _max , and the corresponding amplified digital signal is M _max .

The control process is shown in Figure 2. The speed V _fitness generated by the actual fitness exercise is converted into a digital signal M _fitness by the speed sensor, and then transmitted to the automatic speed controller for n-fold amplification to _set M, and the multiplied and amplified digital signal The signal M _setting is sent to the controller system, and the stepless continuous adjustment of the output voltage U _setting can be realized by adjusting the duty cycle, thereby driving the stepless continuous speed regulation of the motor. Finally, the stepless continuous linear transformation control between the fitness movement speed V _fitness and the motor speed V _motor is realized. The faster the kinetic energy provided by the rider, the faster the electric vehicle will travel.

Among them, the range of n can be set continuously from 1 to 3, and M _setting =n×M _fitness , but when n is set to 1, the speed of fitness exercise is equivalent to the speed of the driving motor, that is, V _fitness =V _motor .

When M _setting ≥ M _max , U _setting = U _max , then V _motor = V _max .

The kinetic energy generated during the fitness process can also charge the battery, which is environmentally friendly and energy-saving.

If the speed governor is switched to a manual speed governor, the automatic speed governor does not generate the M _setting signal output, and instead the signal M generated by the manual turning _handle is sent to the controller, and the rest of the motor control principle is the same as that of a conventional electric vehicle. different. The manual derailleur option is set so that when not working out, the bike can still be used as a regular e-bike.
